Trihalomethanes (THMs) are commonly found outside the water system in any environment where chlorine interacts with organic compounds such as in swimming pools, hot tubs, and even chlorine bleach used for household cleaning and washing.

THMs in the water system are a byproduct of the water treatment process. They form when natural organic material, such as the decaying vegetation commonly found in lakes and reservoirs, reacts with chlorine used to treat the water. This reaction produces disinfection byproducts, the most common of which are THMs.

Manganese  TCEQ website listing for all Manganese sample results. The Concentration should not exceed .05 MG/L

The state lists manganese as a secondary constituent because it is a nutrient that is not harmful to humans or animals. Manganese is a nutrient that most Americans need and are deficient. It is just unsightly and not very palatable.

 The list below is just an example of the natural manganese we come in contact with every day, not just in our water.
